Impulse is defined as the change in momentum resulting from a force applied over time, typically expressed as the product of force and the time duration of that force. In a golfer's long drive, a greater impulse is generated due to a longer contact time and higher force compared to a short chip shot, which involves less force and a shorter duration. Similarly, a boxer's knock-out punch delivers a much larger impulse than a jab, as it involves a greater force and a longer impact time. In baseball, a homerun swing generates a higher impulse than a bunting action due to the increased force and follow-through involved in the swing. Understanding these differences in impulse is crucial for analyzing the effectiveness of each action in their respective sports.
